Because of some microtechnology I have put super light and light odds and ends by itself.

1.)Stealth Systems

A. Electronic Stealth Systems: Allowing Mecha not to be seen to sensors. For the systems below the weight will be 50 pnds each level, and will take up 3levels/.5 space.
1. Sensor Jamming System: Makes you harder to see through enemy sensors but not visual sight.
Levels from -1 to -6 each level costs 10,000 credits per level and makes it harder for an enemy to see you. So take the level and apply it to the opponents die roll. The drawback being they might notice that they're sensors are being jammed before you can attack.
2. Targeting System Jamming: Prevents targeting systems from locking on to you but does not stop seeing you.
Levels from -1 to -6 each level costs 20,000 credits per level and makes it harder for an enemy to lock on to you. So do same as above.
B. Cloaking Systems: Allows mecha not to be spotted by visual and in some cases sensor systems.
1. Basic Cloaking: Protects versus visual only can't fire and stay cloaked and if you fire you must wait until the next round to recloak. Cost:750,000 credits.Weight:200 pnds Spaces:.5

2. Active Cloaking: Provides full protection versus visual and mecha sensor detection but you can't fire and stay cloaked and if you fire you must wait for the next round to recloak. Bonuses:+3 to init and +1 to attack Cost 1.5 million credits Weight:400pnds Spaces:.5space

Add ons to cloaking devices. Each add on will weight 50 pnds and take up 1/4 a space
1. Spectrum Cloaking System: Cloaks from infrared, ultraviolet and other methods. Beware this does not mean your engine trail is masked just the mech just the engines themselves. Cost: 500,000 credits

2. Magnetic Cloaking System: Cloaks the Magnetic output of your engines and weapon systems. Cost: 500,00 credits

3. Firing while Cloaked System: Allows to fire ranged weapons without giving your position away. Cost 1.5 Million credits

4. Combat Recloaking system: Allows you to recloak while in plain view or cloak immediately after decloaking without waiting for the next round. Bonus: -2 for attackers on the next action only involved in attacking mecha equipped with this device. Cost: 1 million credits

Package of all add ons and Active stealth will Cost: 8 million and weight 400 and take up 1 spaces.

Note: If the package is taken, you are not totally invisible to the M.O.S.S. which will be discussed later.

C. Stealth System: We all know what stealth systems on todays jets, well its the same thing here. Very sharp edges and low angles to deflect the radar of enemies, with modifications to the propulsion systems and engines to make the mecha move silent, and leave no heat or radiation trail thus making invisible to the M.O.S.S. which will be explained in the Anti Stealth Systems later on. Bonuses: +3 init and +1 to attack. Cost: 7.5 million credits.Weight :takes up 10% of mecha weight. Spaces:0

D. Painted Stealthing: A compound that when painted on will absorb the radar, infrared and ultraviolet waves used by sensor systems. Drawback is that as the mech takes damage areas will no longer be able to absorb the waves used in the before mentioned sensor systems. An area that takes 30% damage to an area will make that area fade in and out of sensor monitors and any damage over 65% + will make that area not able to absorb the sensor system emitions. Bonuses: +1 init Cost: 50,000 credits each paint job

A. Counter Measures Vs. Electronic Stealth Systems to counter a sensor jamming systems
Each of the sensor jamming systems have a counter measure versus them the cost is exactly the same as the jamming system above but for each level you buy you get to add the level to the modifier made by the jamming system itself. If the counter measure exceeds the jamming system modifier the max bonus to hit that the counter measured mech gets is +1. (For example the jamming mech has a +2 sensor jammer and the enemy mech has a +5 counter measure versus the sensor jammer type the the enemy mech gets a +1 to hit the jamming mech)
B. Anti-Stealth System there really are no anti stealth systems but I am putting the M.O.S.S. here, it really is a new sensor but I fealt it belonged here because if the mech doesn't have the right equipment then this system picks them up with no problem.
The M.O.S.S.,which stands for Multi Optics Sensory System, is a system that scan for many things at one time, it scans the normal spectrums (IR, UV, X-ray, microwave, and many others) while simultaneously scanning for magnetic, vibrations, motion, energy sources, radiation, and thermal heat trails. Cost: 7.5 million credits Weight:250 pnds. Spaces:1

This system is ideal for a recon unit.

A. Radio and Radar Tracking System used to track the radio and radar signal back to its source. Cost:3 million credits. Weight:250 pnds Spaces:.5

B. Ultra Radar increases the radar of the mech using it by 10 times the sensor range. Cost:6 million credits. Weight:250 pnds Spaces:.5

C. Target Identifier after your locked on to a mech would you like to know what type of mech and who it may belong to,if thats what you like then this baby is for you. Cost:5 million Weight 250 pnds Spaces:.5 Note: This system will be loaded with mechs that the DM deems fit. I would suggest most mechs from the books pertaining to Earth and maybe a few of the Phase world books.
